I'm the guy who asked "I'm 5'7β 160. What size would be best for me?β Me ordered before I got a reply, I usually wear a medium sized t-shirt and although the seller said "recommended size 2XL" (they were willing to accept returns if it didn't fit) it fit me perfectly! So it fits - be it for training or superhero - snug but not too tight and without loose folds. If you want your t-shirt to fit like this, use your t-shirt size - it worked for me. Bonus points for receiving NEXT DAY delivery during the holiday season no less!Very happy.Customer.
